Detailed Solution:
The correct answer is “24 January”.
Uttar Pradesh Day, celebrated on January 24 each year, commemorates the foundation of Uttar Pradesh as a state in India.
On this date in 1950, the erstwhile United Provinces, a British-era administrative region, was officially renamed "Uttar Pradesh" as India transitioned to a republic and established its constitution. The day serves to honor the state's rich history, diverse culture, achievements, and ongoing development.
The idea of celebrating Uttar Pradesh Day was proposed by former Governor Ram Naik in 2017, and the state government officially declared January 24 as Uttar Pradesh Day.
